Backup job of VM/CT fails

[Gilgamesh]

When I try to make a backup of that CT it fails. Other backup work normal just not that one. I'm not professional enough make sense out of that ERROR. Does someone has an idea?

could you also post the container config? anything particular about that container?

 

[Gilgamesh]

How do I get the config?

Was created by proxmox helper script from https://tteck.github.io/Proxmox/.

Audiobookshelf LXC

Works good. Except I can't macke backup.

Why is "/var/tmp" a CIFS mount?

> INFO: filesystem type on dumpdir is 'cifs' -using /var/tmp/vzdumptmp281683_122 for temporary files

I would try to use a unix filesystem there (xfs, ext4, zfxs, nfs).

It's on a TrueNAS drive. There is no issue with 15 other LXC backup files on that Cifs mount. It's just that single container.

I have no idea what that script does inside the container, but you can try running rsync manually (you might need to replace the PID if you've rebooted/migrated the container in the meantime (pct status 122 --verbose gives you the current PID, in the example below it was 3857244):

mkdir /var/tmp/test
rsync -vv --stats -h -X -A --numeric-ids -aH --delete --no-whole-file --sparse --one-file-system --relative '--exclude=/tmp/?*' '--exclude=/var/tmp/?*' '--exclude=/var/run/?*.pid' /proc/3857244/root//./ /var/tmp/test
rm -rf /var/tmp/test
